Title: Formation of metallic pattern
Inventor: OHASHI HIROYUKI
IPC: H01L21/288
Filed: 1985-03-20
Abstract: PURPOSE:To prevent the generation of heat when a metallic pattern is formed by laminating many metallic plated layers to increase the aspect ratio of a fine metallic pattern and also to reduce the resistance of a magnetic circuit. CONSTITUTION:Both a metallic film 3 and a contact film 2 are provided on a substrate 1, and a photoresist 4 is applied to these films. Then the 1st plated layer 5 and a photoresist 6 of the 2nd layer are applied on the exposed part of the film 3 excluding the mask 4. The photoresist on the layer 5 is removed by the exposure and development processes. The 2nd plated layer 7 is formed on the layer 5, and both photoresists 4 and 6 are removed. Then both films 2 and 3 held between both plated layers are removed. Thus a fine metallic pattern having 1:1 aspect ratio is obtained by setting the pattern space of the photoresist mask at 4mum.

Title: Image forming device and electrifying roller
Inventor: SAKAI HIROAKI
IPC: G03G15/02
Filed: 1998-02-23
Abstract: PROBLEM TO BE SOLVED: To prolong the service life of a photoreceptor drum by preventing the photoreceptor drum from being partially shaved by an electrifying roller. SOLUTION: The electrifying roller 21 is provided with an elastic layer whose surface is coated on a core bar. Then, the end surface of the elastic layer is cut so as to be inclined with respect to the axis of the roller 21. The inclined angle of the end surface is set to be 3 deg. to 45 deg. with respect to the perpendicular of the axis of the elastic layer so as to distribute the partial shave of the drum by the end part of the roller 21. Since the end surface of the elastic layer of the roller 21 is inclined with respect to the axis of the roller 21 or the end surface of the elastic layer is corrugated, the partial drum shave by the end part of the roller 21 is distributed on an image carrier. Thus, the service life of the image carrier can be prolonged and a cleaning blade is prevented from being turned up by the end part of the roller 21 at the same time.
